SNAP keeps millions of kids fed.
Did you know?
About 4.5 million SNAP recipients are babies and toddlers under age 5.
About 11.1 million SNAP recipients are kids aged 5 to 17 years, who need food for healthy growth, learning, & development.
The federal government has the capacity to continue funding SNAP during a shutdown.

Heat pumps can help alleviate residential energy insecurity in the USA - Nature Energy
In the USA, households with heat pumps tend to cool their homes earlier, and this adoption helps narrow the income-based disparities in cooling usage. Heat pumps can help to alleviate residential energy insecurity and contribute to making energy more affordable and homes more comfortable, especially in the summer.

We found that when households adopt heat pumps, they start cooling earlier this getting to feel more comfortable—without using more energy overall.

If we are ever going to address the energy inequities in this country we need to look at housing stocks inequities and energy infrastructure in the home.
IMO the most interesting finding we had here was getting beyond access to functional cooling usage.
@destenie.bsky.social et al. have found suppressed usage due to affordability burden, but here we also find equipment (AC unit) failures limiting cooling protections.

Our new paper in @urbanstudiesonline.com examines thermal inequities for US manufactured housing residents due to (1) less central AC access, (2) more AC breakdowns & (3) greater energy burdens. Terrific collaboration w/ @gregspierce.bsky.social, Matt Barnett & Sara Hughes. doi.org/10.1177/0042...

When I hear people talk about jobs impacts of AI it is all about loss, rightfully so given the disruption. But I am wondering if we should be talking about the electricians and trades people needed to enable AI. Since I can't google anything without AI these days I don't think its going anywhere.

We need more housing & we need it near transit. It’ll reduce traffic congestion & carbon emissions & increase transit ridership & affordability.
